Problems solved by technology

Because MRI requires a very powerful magnetic field and precise measurements of the molecular movements created by an electromagnetic (radio-frequency) pulse, any distortions that may occur from nearby electrically conductive or magnetic materials will degrade the resulting image data.
However, many tools and devices that are common to other interventional medical procedures are not available or have yet to be developed for use during MRI.

Embodiment Construction

[0052]Referring now to the various figures of the drawing wherein like reference characters refer to like parts, there is shown in FIG. 1 a positionable holding device 20 constructed in accordance with one exemplary embodiment of this invention. The device 20 is arranged to be used with any type of magnetic resonance apparatus (e.g., an MRI scanner) or other diagnostic and / or therapeutic apparatus which necessitates the use of non-metallic or magnetic resonance safe adjuncts when in the vicinity of the apparatus. The device is in the form of an elongated arm 22, a base assembly 24 located at the proximal end of the arm and a holding assembly 26 located at the free or distal end of the arm. The base assembly 24 is arranged for manually mounting the device onto any desired structure, e.g., a table 10, of the magnetic resonance apparatus (not shown). The holding assembly 20 is arranged for ready mounting and dismounting (i.e., releasably mounting) any desired end effector 28 on the fre...

Abstract

A device in the form of an elongated articulating arm having a base for mounting it on or at the MRI apparatus. The free end of the arm is arranged to releasably mount any type of device, e.g., a clamp, a bracket, a biopsy needle guide, etc. The arm includes a plurality of interconnected segments each of which is arranged to pivot with respect to adjacent segments. A flexible elongated adjustable tensioning member extends through the arm between the base and the distal end portion to enable the arm to be moved or bent into a desired shape when tension is released and then held in that shape when tension is applied.
